the fossil species. Having temporarily taken Mr. Barrett’s 
l)lace in Jamaica, Mr. Wall, in conjunction with Dr. Dun- 
can, communicated a very important notice of the geolog>- 
of that island to the Geological Society. That communica- 
tion embodied de.scriptions and figures of many of the fossil 
corals of Jamaica. 
The remains collected b}* Mr. Barrett in Jamaica having 
been deposited in the British Museum, were examined 
by Mr. Carrick Moore, who communicated in 1863 a notice 
of them to the Geological Society. In 1865, being then in 
London, I undertook at the request of Mr. Woodward the 
description of these fossils, for which I had been prepared 
b}' several years study of the fo.ssils and recent shells of the 
West-Indies, and at the .same time I described and enume- 
rated other fossil molluska and echinoderms from the West- 
Indies, including Trinidad. Sub.sequently I communicated 
to the Geological Societ\' a resume of what was known of 
the geolog\' and paleontology’ of the tertiary formations of 
the West Indies, enumerating the fossils and describing 
such new species as were accessible to me.* 
It will of course be understood that the present paper 
relates to the tertiary geology only of Trinidad and the 
Caribean area. But by’ way of parenthesis I may allune to 
the secondary’ rocks of Trinidad, the conclusions as to 
which have been ba.sed upon the researches of Boussingault, 
Roemer, Karsten, Lea, \"on Buch, d’Orbigny, &c. On this 
subject I have published a paper in the “Geologist.” The 
crectaceous rocks of Jamaica have been treated of by’ Barrett 
and Woodward, and the latter has de.scribed from that

yVest-Indian Geology, and to it therefore I would refer those desirous 
of working at the subject. It was published in the 22nd vol. of the 
Quarterly Journal of she Geological Society. London 1866.
